I'm looking solution for data only USB-cable for ESP32 <-> WIN10.

I made cable where only data (white& green) are connected. Unfortunately it seems that Windows is not finding the USB-port with this cable when the board is power from other source.

Is there away to connect to board with data only cable and how the cable should look like?

At the very least, you need ground (the black cable) as well.

The ground didn't help.

I too am trying to use a Micro-USB data only cable with no success. I am powering the ESP32 DevKit separately - it works just fine, but I do need to a working setup with a data only cable. Espressif has made claims that one can use a data only cable, but so far no luck. Please help!

I used the green and white data wire with the black ground and it works, just leave out the red + wire
